摘要:

唧泥是机场水泥混凝土道面常见病害,会进一步形成脱空病害,影响道面结构承载能力。通过对唧泥的形成机理进行分析,提出了在道面结构设计中提高道面抗唧泥性能的3 种措施,分别为提高道面厚度、接缝传荷能力和基层强度。并采用有限元软件分析了不同措施的工程效果,其中提高接缝传荷能力效果最佳,提高基层强度次之,提高道面厚度效果最差。

Abstract:

Pumping is a common defect of cement concrete pavement,and it would further cause the void defect,which has much effect on the loading capacity of pavement structure. Through analyzing the formation mechanism of pumping,this paper proposes three measures to improve the anti-pumping performance of airport concrete pavementin structural design. These measures are increasing the thickness of pavement,increasing the joint load transfer capacity and increasing base strength. Using the finite element software,the effects of these different measures are analyzed. The result is that increasing joint load transfer capacity is the best,increasing the base strength takes second place,and increasing the thickness of pavement is the worst.

Key words: airport, anti-pumping, three-dimensional finite element, cement concrete pavement, void, structural design
